Was Japan’s pan-Asian union a genuine liberation movement or a facade for imperial expansion?
In short: The Greater East Asia Co-Prosperity Sphere promised an end to Western colonialism, uniting Asian nations under Japanese leadership. While marketed as a path to regional self-sufficiency and spiritual renewal, the reality was a brutal resource-extraction machine that ultimately served only the strategic and economic interests of the Japanese Empire.
Coined by Foreign Minister Hachirō Arita in June 1940, the Sphere was framed as a defensive alliance against Western imperialism and Soviet communism. Japan claimed its role was to liberate Asian peoples from foreign control, replacing Western materialism with a shared spiritual essence. Yet, internal documents like the 1943 study on global policy revealed a different agenda: the consolidation of Japanese hegemony. The state viewed itself as the superior nucleus of a new order, with other nations serving as protected subordinates under the Yamato race.
In practice, the project functioned as a mechanism for wartime survival. Facing severe trade embargoes on oil and steel from the United States, Japan seized Southeast Asian territories to secure raw materials. The administration of these regions was ruthless; local economies were forcibly reoriented toward Japanese military requirements. Agricultural experiments, such as replacing sugar crops with cotton in the Philippines, failed catastrophically due to poor planning and lack of technical expertise, causing widespread famine and economic collapse. By the end of the war, the term 'co-prosperity' was widely mocked by locals as a euphemism for servitude.
The diplomatic facade of the Sphere culminated in the 1943 Tokyo Conference, where Japan hosted leaders of puppet regimes from Burma, China, India, and the Philippines. Despite the rhetoric of equality, these representatives held no real power, and the event served primarily as propaganda. As wartime leader Ba Maw later reflected, the Japanese military’s insistence on a singular, Japan-centric perspective made genuine cooperation impossible. By the time of Japan's surrender in September 1945, the project had failed to secure the trust of its intended partners, leaving behind a legacy of resentment rather than the promised regional unity.
